IMPROVEMENT IN SPINNING-FRAMES.-

Specification forming part of Letters Patent No. 169,507, dated November 2, 1875; application filed l March 27, 1875.

To all whom it may concern:

Be it known that I, JOHN E. ATWOOD, of Willimantic, in the county of Windham and State of Connecticut, have invented certain Improvements in Spinning-Machines; and I do hereby declare lthat the following is a full, clear, and exact description of the same, ret'- erence being had to the accompanying drawing, which forms part of this specification.

My invention consists in, first, a novel combination of two or more spindles and their pulleys on opposite sides of the frame, two horizontal shafts and their pulleys, and endless band, and .an idler tightening-pulley, whereby a single band is made to drive spindies on opposite sides of the frame, and a uniform tension of the band under all circumstances is obtained 5 second, the combination, with the idler-pulley above mentioned, of a counterbalanced weight, to prevent too great friction and Wear of lthe bearing.

In the accompanying drawing, Figure l is atop view of a machine embodying my invention. lFig. 2 is a vertical section taken in the line '90 :r of Fig. l. Fig. 3 is an enlarged vertical section taken in the line y y of Fig. l.

A represents the frame of a spinning-machine, having spindles on opposite sides, the spindles B on each side being arranged in pairs, as shown. G1 C2 represent two horizontal shafts, arranged lengthwise of the frame, and carrying pulleys all d2, there being one pulley on each shaft for each pair of spindles.

- 'lhe shafts G1 (l2 are connected by belting or gearing, so as to revolve in the same direction and at the same speed. On one side of the frame is a hanger, e, to which is pivoted a lever, f, one end of which carries a weighted idler-pulley, F, and the other end is provided with acounter-balance weight, G, which weight may be adjustable. An endless band, H, passes around the whirls or pulleys b of the spindles B', over the pulleys d1 d2 ofthe shafts C1 G2, and under the idler-pulley F, which is preferablyv arranged immediately under the space between the pulleys dfdz. By this arrangement of the endless band and the pulleys d1, d2, and F, with relation to each other and the spindles, a single .band is made to drive the spindles on both sides of the frame, and by arranging the spindles in pairs the same band is made to drive four spindles, or two 4on each side of -the frame. The idlerpulley F not only serves to enable the band to be arranged as described, but, by its weight, it automatically preserves the proper tension of the band and secures uniformity of speed, and by means of the counter-balanceGr, the pressure of the idler is regulated and excess ot' friction and wearpof its bearing is prevented. The boxes I J, in which the spindles have their bearings, are of such construction that each spindle is provided with a stepbearing and a bolsterbearing, the lower box I `having its lower end closed, and forming the step-bearing, and the upper box J having both ends open, and forming the bolster-bearing. Each box is formed with two bearings, at a distance from each other corresponding with the distance at which the spindlesv are located when arranged in the usual manner. The boxes are attached tothe frame by screws lo, and are prevented from lateral displacement by means of tongues Z1 on the boxes, and grooves l2 in the frame. When the spindles are in place in the boxes, their whirls or pulleys b occupy a position between the top of the lower box and the bottom of the upper box, so that the friction is divided between the step-bearing i and the bolster-bearing j.

By this construction oi' the box with double bearings, I provide simple, cheap, and effective bearings for each pair of spindles.

In the upper portion of each of the boxes l J, is a chamber, M, provided with two ducts, m m, leading to the bearings 'it' or j j. In the chamber M is placed the lubricant for the spindles, consisting ofoil or grease, or of fibrous material saturated with oil.

By this arrangement of the oil-chamber with relation to the bearings, one chamber is made to supply the lubricant simultaneously to both the bearings in the bok.

The oil-chambers M are covered by caps or plates P, resting on the tops of the boxes. Each cap is provided, near its ends, with perforations, through which the spindles pass, by which means the caps are held in place without the us'e of screws, bolts, or other fastenings.

What l claim as new, and desire to secure by Letters Patent, is-

1. The combination, with two or more spinand its lever f, of the counter-balance weight dles on opposite sides of the frame, and two G, as shown and described, lfor the purpose horizontalshaits arranged lengthwise of the specified. frame, of the two pulleys d1 cl2 on said shafts,
